Why do some people get headache so often?

There are a host of different reasons, some more serious than others. Dehydration, stress, certain foods and other factors can all trigger headaches.

Some maybe related but usually we get headaches from a lot of things. The weather, Stress, Improper Lifestyles, those are the things that I think that give people headaches.

i guess one of the reason was eating habit..everyone must have a specific time to eat..sometimes we tend to forget it maybe because so engrossed here or doing some chores or workloads..a friend told me that her nephew was experiencing habitual headaches and wondering why so they consulted it and explained to them that there are many factors that may cause it and the most common one is this.it does not really means or in relation to brain cancer or whatever..unless you had done some lab test or ct scan on it(to be sure)

Many people don't drink enough water during the day,and that leads to dehydration,one symptom of which is getting headaches..before panicking about having or getting Brain cancer,try drinking a pint of water!

No, no cancer. I have migraines about five times a week. There's really nothing I can do but to just live with it. I take medication to numb some of the pain, but ti never goes away compltely. When it's not too forceful I simple feel a slight pressure on the side of my head. I've had them since I was a teenager, about thirteen I think. It really sucks, but I'm so used to it now.

I have suffered from migrains for over 20 years. I have had CT Scans done and MRI's to rule out cancer. They never found anything that would be bad. Some people are just bothered by things. I have a hard time with certain smells like room sprays, perfumes, and cleaning products. If I eat to much chocolate I will often get a migrain. Stress and blood pressure levels also cause headaches.

I think it can be a blood thing as when I used to get migraines I used to take apple cider vinegar in water which in fact is a blood thinner...it can also be in the family as all the girls in my family seem to suffer from migraines, it can also just be stress I guess...

It can be related to cancer, but not always. Most of the time, headaches are caused when the skull is putting pressure on the brain. Another way it can be cause is through hard impact to the skull through something like a football tackle. Luke
